TAI LORS SH EARS.

SPECIFICATION forming part of Letters Patent No. 280,047, dated June 26, 1883.

Application filed May 12, 1883. (No model.)

To all whom it may concern.-

Be it known that I, LoUIs KULLY, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Tailors Shears, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to an improvement in that class of shears in which the pivot is placed at one side of the line joining the edges of the blades, and is adapted chiefly to heavy tailors shears, in which the thickness of the metal about the pivot permits the use of the adjust ment herein shown.

The improvement consists in the combination, with the fulcrum, of an adjustable block adapted to fit in a slot in one of the blades, and in an adjusting-screw adapted to hold the fulcrum pin or bolt securely against the said block.

The object-of the invention is to furnish a means of sliding one blade toward the other edgewise as the edges of both are worn and ground away, and the construction employed will be understood by reference to the annexed drawings, in which Figure 1 is a sideview of the shears open. Fig. 3 is a separate view of the right-hand blade. Fig. 4 is a section of both blades on a line indicated by a: x in Fig. 3, and Fig. 5 is a detached view of the fulcrum-block.

A is the right-hand and B the lefthand blade; 0, the fulcrum=bolt; D, the slot in which the movement of the bolt is efiected; E, the block in which the bolt is pivoted; F, a clampbolt to regulate the pressure of the blades together; G, aslot in blade A for the movement of the same as the fulcrum is altered, and H the adjusting-screw for effecting such alteration when required.

The blade A is formed with a top ear, I, for the fulcrum-bolt C, and a bottom ear, J, for the slot G; and the blade B isformed with a long ear, K, for the slot D, and with a curved slot, L, in which the bolt F plays when the shears are opened.

A B are the handles of the blades A and B, and a a are dotted lines in Fig. 1, showing the position of blade B when closed. It will be observed that the blades lap on one an other considerably when closed, but that when open they will cut all the way up to the lug J, which results from the position of the fulcrum 5 so far to one side of the line a, and produces a shearing cut, as indicated in the dotted lines b b. These lines are drawn with the fulcrum O as a center, and represent the oblique movement of the blade B toward the blade A.

The block E, when new, fits the slot D at both ends, but is intended to be filed off at the end nearest the slot L when the edges of the blades have been worn and ground and require setting toward one another. Such grinding is always done by a skilled workman, and such a oneis competent, and always provided with suitable tools to file off the end of the block E and set the edges of the blades in their original relation. This adjustment consists, practically, in moving the hole for the fulcrum toward the edge of the blade B as the same is worn and ground off and such movement necessarily moves the whole blade sidewise toward the fixed fulcrum-pin 0, whose position in the blade A is unchangeable. Such side movement of the blade B of course brings the clampingbolt F nearer the fulcrum, as the slot L is carried with the blade B; and the ob ject of the slot G is to permit such side movement of the bolt F without at all affecting its operation. The bolts 0 and F are provided with heads and nuts and-washers 0,.to cover the slots D, L, and G; but the bolt may be formed in any other way-as, for instance, the 8 pin C might be tapped into the blade A and have only one nut at the front end.

From the above description it will be seen how securely the blades are fastened together, and yet are adapted by merely filing the block E at the end marked (1 in Fig. 5, and turning the screw H to jam it firmly against the lower end of the slot D, to be adjusted toward one another at pleasure. The jamming of the block fast in the slot does not cramp the pinC 9 at all, as the latter turns freely in the hole marked 0 in the block in. Fig. 5. Shears with my construction are therefore adapted to wear much longer than those without the adjustment Ihave provided, as the blades can be I00 restored to their original relations after grindand the screw H, the whole arranged and op- 10 ing. erated as shown and described.

-I am aware that it is not new to adjust the In testimony whereof I have hereunto set fulcrum C to secure a shearing cut with the my handin the presence of two subscribing 5 blades, and therefore claim my invention in witnesses.

the following manner: LOUIS KULLY.
